>>>>Don't mean to hijack this thread... Have a few other questions about US60.. I'm putting one together now with a tower 75.. Anyway, have heard mention several times the need to reinforce the landing gear block, as well as 'pin' the firewall.. Anyway, this is my 2nd plane and am not sure about the best way to accomplish these two things.. Can anyone who has done this describe the process? I assume the pinning uses dowels into the fuse/firewall, but you don't have much room to work with here! >>>>>

Immediately replace the metal landing gear bolts with nylon ones. I simply replaced the stock metal bolts with nylon ones, and then drilled and tapped for a couple of extra nylon bolts. I went with little 10-32 jobs and have 4 of them holding the gear on. For the extra ones, you don't even need to install blind nut. Just drill and tap the hardwood block and then harden the threads up with some thin CA.

As far as pinning the firewall, I used servo screws, one in the bottom and two on each side. Real easy!
